Many of the city’s yellow-cab drivers are calling in sick because they fear being attacked after Tuesday’s terror onslaught.

“They’re all afraid they’ll be hit by angry people,” cabby Luis Almonte said of Muslim drivers.

“People throw rocks at them. They spit at them. Last night, someone broke a driver’s windows on 56th Street between Seventh and Eighth avenues,” said Zenaida Rodriguez, who is acquainted with many Pakistani drivers in her Flushing, Queens, apartment building.

Irene Kay, manager of Taxi Club Management Inc., which operates about 500 cabs out of Queens and Manhattan, said the driver turnout was about 50 percent yesterday.

But Allan Fromberg, spokesman for the city’s Taxi and Limousine Commission, said, “Compared to yesterday and the day before, today’s service was moderate to heavy.

“Things are rapidly returning to normal and we’re happy to see how they [taxi drivers] have stepped up to the plate – in true New York fashion.”

It’s not just Muslims who are fearful.

“We’re all afraid, because New Yorkers don’t know the difference,” said Rajinder Uppal, a Sikh driver.

“They think if you have a turban on, you’re Muslim.”

Rodriguez said she bought American flags for the drivers in her building and urged them to put them on their cars.
